Hey Shawn,
The bipe looks good on paper. Are you planning on kitting it or at least building a few? Going the composite fuselage route is a pretty serious commitment and a lot of work. There have been a few other threads here showing scratch built composite fuselages pulled from a plug. It would be nice to do the design in CAD then through a hunk of wood on a CNC lathe and watch the chips fly.
I think your idea of putting the aileron servos in the interplane struts has merit. Biplane wings are typically so thin the aileron servos have to be mounted on the side. Will you be using 4 aileron servos? You might consider making the servo mounts part of the wing and have the interplane struts attach to the servo mount. Then you don't have to deal with linkage detachment every time you take the plane apart. Plus you could make the servo mount/interplane strut mount removable from the wing, too; so a three piece interplane strut. The strut would be the only part that was regularly removed for transportation.
Good luck! I am looking forward to following the build!
